What does the forward slash mean in app.get('/',function(){…}); in express.js?

Question

我刚刚开始学习express.js，在那我们做app.get（'/'。function（）{...}）;，我想知道那是什么意思。我试图研究Google，但实际上无法获得，而不会过于技术化就可以简单地描述它。

Answer 1

Lets say you're running your server on localhost port 8080. Then the root URL of your server is http://localhost:8080 .

Thus when you write

app.get('/', function(request, response) {
  console.log('hi');
})

You're saying

When someone sends an HTTP GET to http://localhost:8080 , I log "hi" into the console.

• / means just your root URL
  • /example in contrast would mean http://localhost:8080/example
• function(){} is what you want to do in response
